Incidence relation (namely corresponding relationship).
It should be understood that the first signal (certainly, can also should be managed in application scenes for uplink reference signals
Solution any other can also can be carried out signal characteristic acquisition for establishing fingerprint base other than uplink reference signals
Row signal), it still may include signal reception power that signal, which receives feature, and it can corresponding include that signal sends function that signal, which sends feature still,
Rate, and the transmission power for sending the equipment of uplink reference signals is essentially identical.
It should be understood that the above-mentioned makeover process in the present embodiment is an optional mistake according to concrete application scene
Journey.For example, before executing above-mentioned makeover process, can also first acquire in a kind of example and judge first community and second community
The middle signal for sending above-mentioned first signal sends feature, sees whether the difference of the two reaches a preset threshold value, if so,
Into subsequent amendment step；Otherwise, subsequent makeover process can not be entered.For example, in a kind of application scenarios, when first
The signal transmitting power that cell and second community send above-mentioned first signal is identical or essentially identical, then can not enter above-mentioned amendment
Step then needs to enter above-mentioned amendment step and corrects and then generate when the transmission power difference of the two is greater than given threshold
Location fingerprint library.Certainly, in some instances, above-mentioned judgement can not be done and is directly entered amendment step, to adapt to various applied fields
Scape.
It should be understood that in addition to feature foundation and position can be received by the signal using the first signal in the present embodiment
To generate outside location fingerprint library, the signal that the first signal can also be used sends feature and establishes to be believed the incidence relation of confidence breath with position
